Implement UI components for configuring command zones when creating
new games.
New components:
- GameZoneOptionsWidget: reusable widget for zone configuration
- DlgLocalGameOptions: local game setup with command zone options
Integration points:
- DlgCreateGame: add command zone options to game creation dialog
- WindowMain: wire up command zone configuration in game flow
This allows players to:
- Enable/disable command zones for a game
- Select zone type (Commander, Companion, etc.)
- Configure zone-specific options
